The Zetland Passive House project is the UK's first certified EnerPHit Plus retrofit. Originally built in 1894, this Passivhaus project is intended to provide a blueprint for retrofitting the UK's 8 million hard to treat homes built prior to 1930. Using natural, breathable building materials and reusing much of the existing fabric, the project is a pioneering example of sustainable low carbon retrofit.
The homes achieved a 95% reduction in space heating demand and a 7-fold reduction in carbon emissions. An 11kW PV system powers the smart hot water tank and a 2kw post heater piggy backing the MVHR system, removing the need for a traditional central heating system.
While Passivhaus certification was a key part of the design, there were several other sustainable design philosophies and technologies adopted in order to minimize its carbon impact:
- Working within the existing footprint, using tiny house design principles to prevent the need to extend, reducing embodied energy
- Retention of existing fabric to minimise waste and maximise thermal mass potential
- Breathable, natural, petrochemical free building fabric
- Healthy internal environment (air filters, humidity control, VOC and CO₂ absorbing materials etc.)
Honouring the UK's architectural history was just as important to the design team as creating a low carbon home. This property features the first Passivhaus stained glass windows and doors, as well as Victorian-style plaster cornicing and ceiling roses, decorative mosaic tiling, stone steps and ornate porch.
The project has been an invaluable knowledge sharing exercise visited by more than 300 architects, policymakers, developers and thousands of homeowners. The Zetland Passive House has been featured in more than 50 media outlets, including the cover issue of Passive House + magazine.
